MoYu Cube Mat
The quality of the mat is brilliant, and the design is ok. I didn't realise the size of it though, it's actually a speedstacking mat, so it is roughly double the length of a speedcubing mat. Nothing wrong with that if you have a large table, but something to be aware of if you're using a small desk for practice.
Compatible with my qiyi timer and fits well on small tables (it is about 50x35cm)
